To all wwm'z't may concern 4*Be it known that I, HENRY E. RATHBN, a citizen of the United llloi'cester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Porch- Shades, of which the following is a speciliation.

My invention relates to blinds, or shades, and more particularly to a porch blind or shade, which is adapted to be rolled up, and which is preferably made of a series of thin strips or slats of wood, secured together and held in place by flexible strands or threads, which are interwoven, or twisted about said strips or slats, in any usual and Awell known wa hlly invention particularly relates to the top edge, and to the bottom edge of the shade, andthe object of my invention is to provide an improved top edge, and bottom edge, on shades of the. class referred to.

My invention consists in certain novel features of construction of my improvements in porch shades as will be hereinafter fullv described.

Referring to the drawing: Figure 1 is a front, or back view of a shade embodying my improvements. Fig. 2 is a section, on line 2, 2, Fig. 1, looking in the direction of arrow a, same figure. Fig. 3 shows, on an enlarged scale, a section, on line 3, 3, Fig. 1, looking in the direction of arrow a, same figure, showing the strands extending above the top edge of the shade, and Fig. 4 shows the three strips, forming the top edge, or the bottom edgev of the shade, moved apart,

In the accompanying drawing, 1 are thin strips or slats, forming the body of the shade, and preferably of wood, 2 and 2 are the flexible strands or threads, arranged in pairs, and wrapped or twisted about the slats 1, in any usual and well known wav, to secure them together, and hold them in place` and allow the shade to be rolled up. In this instance one of the strands 2 passes on one side of a slat, and then between a pair of slats, and then upon the opposite side of the contiguous slat, and then between apair of slats, and then upon the opposite side of a contiguous slat, and so on, and the other strand 2 passes first on one side, and then on the other side of alternate slats, in a similar manner, and as clearly shown in Fig. 2.

The above mentioned parts may be of States, residing atV land in the usual and well known construction employed in Aporch blinds 01 shades of the class referred to.

I will now describe my improvements.

The top edge, and bottom edge of the shade consists of three strips or slats, the central one 3, preferably corresponds to the strips or slats 1, in width and thickness, but it is preferably corrugated or grooved longitudinally on each side, as shown in Fig. 4. The two outside strips or slats 4, and 5, each preferably have on their inner side la. series of grooves or recesses, extending in the direction of the length of the slats, as shown in Fig. 4; Vthe strips or slats 4 and '5 are preferably a little thicker or heavier than the strips or slats 3, and are preferably` rounded on their outer edges. In completing the top edge, or the bottom edge of the shade, the strip 4 is applied to one side of the strip 3, and the strip 5 to theother side of the strip 3, the strands 2 and 2 extend upon each side of the strip 3, 4practice below the outer edge of the strip, as shown in Fig. 3. The strips 4 and 5 are preferably secured to the strip 3 by small nails or rivets 6, preferably passing through said strips on the opposite sides of the strands 2 and 2, see Fig. l. The forcing together of the strips 4 and 5, on the strip 3, in securing them together by the nails or rivets 6, will force the flexible strands 2 and 2 into the recesses in the corrugated surfaces of the strips 3, 4, and 5,

as shown in Fig. 3, and thus firmly secure the ends of said strands to said strips.

The advantages of my improved construction of the top edge, and the bottom edge of a porch blind or shade, of the type referred to, will be readily appreciated by those skilled in the art. It ,is not necessary to turn in the ends of the flexible strands or threads 2 and 2, between the slats or strips 1, or to secure them in any other way, as the corrugations in the strips at the top edge; and at the bottom edge, act to hold the strands or threads 2 and 2 and prevent them from being disengaged from said strips.

It will be understood that the details of construction of my improvements in the top edge, or the bottom edge of porch shades may be varied if desired. and mav be used in connection with anv make of shade. of the class referred to. I prefer to have the central strip 3 corrugated longitudinally on 'inner strip or member being grooved L and 5, and good results obtained. I prefer to have both the top edge of the shade,

"and the bottom edge of the shade, of my improved construction, but if preferred only Vone edge may be of this construction.

Having thus described my invention, What I claim as nenT and desire to secure by Letters Patent is 1. A compound Slat, for the top or bottom of a. flexible shade or blind, consisting of three strips or members of equal Width, or approximately so, secured together, the inner strip or member being grooved or corrugated to afford a strong grip or hold on the cords of the shade or blind.

2. A compound slat, for the top or bottom of a flexible shade or blind, consisting of three strips or members of equal Width, or approximately so, secured together, the or corrugated to afford a strong grip or hold on the cords of the shade or blind, and theV outer strips or members being also grooved or corrugated to cooperate with the said inner strip or member in the grippingror holding action.

3. A compound Slat, for the top or bottom of a flexible shade or blind, consisting of three strips or Amepfgbers of equal Width, or approximately sof* secured together, the inner strip or member being grooved or corrugated to afford a strong grip or hold on the cords of the shade or blind, and the outer strips or members being also grooved or corrugated to cooperate with the said inner strip or member in the gripping or holding action, the said outer strips or members having rounded top and bottom outer edges.

4. A compound slat for the top or bottom of a exible shade or blind, consisting of three strips or members secured together, the outer strips or members being grooved or corrugated, to coperate with the inner strip or member, to grip and hold the cords of the shade or blind.

5. A compound slat, for the top or bottom of a flexible shade or blind, consisting of three strips or members secured together, one or more of said strips or members being corrugated longitudinally to afford a strong grip or hold on the cordsof the shade or blind. Y
